About this test
The light-and-sound repetition game was popularised by an electronic toy released in 1978: a round unit with four coloured pads, each tied to a musical note, playing back an ever longer sequence for you to copy. It was among the first mass-market toys to use a microprocessor, and the format has survived forty years of technical change intact because it tests something very simple and very robust.
What it measures has a name: immediate memory span, the number of items you can hold in order right after perceiving them. Without any particular technique that span sits around four to seven items for unrelated information. That's why most players stop somewhere between level five and eight.
The way past that ceiling is chunking: instead of holding eight separate steps, you build three packets — red-green-green, blue-yellow, red-blue-red — and only hold three units. The second lever is sound. Because each pad plays a different note, the sequence becomes a short melody, and a melody is far easier to retain than a list of colours. The best players practically close their eyes.
How it works
The level shown is the number of sequences you repeated without error; the sequence gains one step per level. A single mistake ends the run, with no second chance. The 0-100 score starts at level 2 and caps at level 18.
